The Facebook page FindAlexJohnson went live last week and had garnered nearly 5,000 likes by Sunday evening. The page is dedicated to finding 32-year-old Alex Johnson of Lexington, who hasn't been heard from since ending a phone call with his girlfriend to answer the door at his home.

Johnson's sister, Cayce Johnson, told the Lexington Herald-Leader, the page has helped spread the word of the disappearance to nearly 80,000 people.

The Lexington police department is investigating the disappearance. It had no update Sunday.
